As would regular equipment or transponder failure to relay that data. There plane wouldn't need to be shot or even damaged at all except for a fried relay or something, especially since the speed seems to stay exactly the same. It's not possible to be involved in such a steep drop in altitude without the speed of the craft shifting a fair amount as well.
